.
(other quantities (such as [‘area’ / ‘pressure’ / ‘electrical resistance’] are derived from these ‘base quantities’ by ‘clear’ + ‘non-contradictory’ equations)
.
(the ISQ defines the quantities that are measured with the ‘SI units’ / also includes many other quantities in ‘modern science’ + ‘technology’)
.
(the ISQ is defined in the ‘international standard ISO/IEC 80000’, and was finalized in ‘2009’ with the publication of “ISO 80000-1”)
.
(the 14 parts of ‘ISO/IEC 80000’ define quantities used in ‘scientific disciplines’ such as…)
‘mechanics’
.
‘light’
.
‘acoustics’
(eg ‘sound pressure’ + ‘sound intensity’)
.
‘electro-magnetism’
.
‘information technology’
(eg ‘traffic intensity’ + ‘storage capacity’)
.
‘chemistry’
.
‘mathematics’
.
‘physiology’
